Many welcomed more research, and some welcomed possible new treatments. But the administration’s embrace of unproven science and approach to autism as a “crisis” has sown deep mistrust.

Sitting on the couch a few weeks ago watching television, Jonathan Gardner saw something that made him text his mother immediately. “Weird question,” he typed. “Did you take Tylenol at all when you were pregnant with me?”
He had seen a news report about a new scientific review finding a possible correlation — though not a causal link — between the use of acetaminophen during pregnancy and a higher incidence of neurodevelopmental disorders. The finding remains inconclusive, and other studies have found the opposite.
Mr. Gardner, a local disability advocate in East Bridgewater, Mass., was diagnosed with autism before he turned 2. His mother, Nancy Gardner, replied that she didn’t take acetaminophen — the active ingredient in the painkiller Tylenol — during pregnancy.
And now she worried that a focus on the decisions of mothers would create unnecessary guilt for parents. “It’s no one’s fault” when a child has autism, she said in an interview.
That’s something that many people with autism and their families were repeating on Monday, as President Trump and his health secretary, Robert F. Kennedy Jr., launched a broad offensive against the mainstream understanding of the condition, including telling pregnant women to resist using Tylenol, despite a lack of proof it causes autism.
“Don’t take it,” Mr. Trump said in a White House briefing where he also delivered flawed medical remarks about vaccines and other science on autism, including urging women to “tough it out” when in pain rather than using acetaminophen. “Fight like hell not to take it,” he said.
The administration pledged to invest $50 million to study the causes of autism, with Mr. Trump and Mr. Kennedy both pointing toward a possible connection with childhood vaccines. No link has been found despite decades of study, and mainstream scientists overwhelmingly agree that autism is a result of a complex mix of genetic and environmental factors that can’t be attributed to a single cause.
Likewise, medical groups on Monday quickly rebutted the president’s warnings about Tylenol, defending acetaminophen as a safe treatment for fever in pregnant women, although it is not recommended for long-term use.
Karen Kossow, 47, of Boise, Idaho, is a mother of two children with autism. She took Tylenol during both of her pregnancies to mitigate the pain from Ehlers-Danlos syndrome, a connective tissue disorder.
She said urging pregnant women to avoid the painkiller when no link to autism has been proven could be harmful. “Having a fever while you’re pregnant can be dangerous,” she said. “Having pain while you’re pregnant can be dangerous.”
Kiara Coleman, whose 12-year-old son Keenan has autism, said she did not take Tylenol when she was pregnant, but thinks it’s important for mothers to know about the potential risks that could come with medication during their pregnancy.
“I just feel that doctors in general need to let parents know: ‘Hey, I know you’re in pain, but I wish I could give you something that’s not going to hurt you or the baby,’’ she said.
The Food and Drug Administration was far more circumspect than the remarks made on Monday by Mr. Trump and other top health officials, issuing a letter to doctors that noted, accurately, that “a causal relationship has not been established” between acetaminophen and autism. It stated that the matter is “an ongoing area of scientific debate.”
Several people with autism said in interviews that while they support more funding for autism research, they have trouble trusting the Trump administration and are worried about its messages that contradict health experts.
“This administration seems to care a lot about autism as a supposed epidemic,” said Colin Killick, the executive director of the Autistic Self Advocacy Network. “It does not seem to care much at all about autistic people.”
The messages about Tylenol can be especially confusing. Emily Sokolowski, who most recently worked with the Autism Society of America, saw it firsthand this week when her brother Adam, 32, who has autism, tested positive for Covid-19.
On Monday morning, when their mother suggested he take Tylenol to ease his symptoms, he was reluctant because of what he had seen online. “I can’t take Tylenol,” he told her, according to his sister. “It’s going to make my autism worse.”
Mr. Gardner, the man who texted his mother to ask about her Tylenol use, said it made him nervous that officials seem to be looking for “something to blame without data and proof.”
He added that some comments from administration officials — including Mr. Kennedy, who said in April that autism “destroys families” — have led to increased stigma toward people with autism, which Mr. Trump on Monday called a “horrible, horrible crisis.”
“There is definitely much more fear about autism,” Mr. Gardner said, adding that the administration was treating it like a terrible disease, “instead of an intellectual disability.”
Jordyn Zimmerman, 30, an autistic woman who communicates through augmented methods instead of speaking, said she would rather see the administration focus on expanding such technology, which she did not have access to until she was 18 years old, and providing other support for people with disabilities.
“When the administration focuses on things like this,” Ms. Zimmerman said in an email interview, “it draws attention away from the things we actually need.”
Lizzy Graham, 36, agreed. “Autism doesn’t need a cure,” said Ms. Graham, a social worker supporting children with autism in Maryland. She was diagnosed when she was in middle school.
But Russell Lehmann, 34, who works as a disability advocate at the University of California, Los Angeles, said he would appreciate a treatment to reduce some of the behaviors that he exhibits, such as sensory overload or the need for a rigid routine.
Mr. Lehmann said he had to drop out of his middle school because he did not receive the support he needed for his autism, an experience he described as isolating. But while he appreciates more money for research, he was dismayed by the way that Mr. Trump and Mr. Kennedy talk about autism.
“Personally and professionally,” he said, “it’s very disheartening.”
